Review on Durable Transparent Security Backpack: The Ultimate Casual Daypack Solution by Jim Dahl

Good quality for what it is. Plastic backpack. Better than most. Get some good quality clear packing tape like Duck Brand Max Strength and use it to reinforce the top and bottom "corners" inside and out and any other places where your bag flexes/flexes a lot. Take some superglue and put small strokes on the black stitching where it starts to unravel or where the long threads are hanging down. I use it in winter and prolonged exposure and use in the cold seems to cause more cracks in the corners and flex points. For those who only spend 15 minutes outdoors in cold weather, this might not be a problem.
